A novel approach to the synthesis of 3-methyl-1H-quinoxalin-2-ones has been described. These compounds were regioselectively prepared by starting from substituted phenylamines and alpha-chloropropionyl chloride through the efficient procedures of acylation, nitration, reduction, intramolecular alkylation, and oxidation.
